很久没写文章了；实在不知道写什么。姑且将一个网友的问题写出来吧。对方问到如何处理一个ora-00600错误；通过日志简单看了一下，是一个非常常见且熟悉的错误；很明显对方没有看过我的blog。

从错误来看；数据库在open的时候报错。针对该错误写过太多的文章和案例了，这里就不多说了。简单说下处理思路：
1、通过bbed 修改该数据块，提交问题事务
2、通过Oradebug poke去修改scn；推进整个db的scn。
需要注意的是，由于网友这里是11204版本，因此按照网上的处理方法就失败了。

可以看到，推进scn后很容易就打开了数据库。后面又提人到说有个文件之前被人重建控制文件丢掉了；现在状态是missing。

对于这个问题，之前blog写过类似问题处理方式，基本上没有别的方法，只能bbed去修改；否则直接恢复会报错：

处理方式就是直接bbed修改文件头就好了；这里不再描述了。

对于Oracle实在没有太多可以写的东西了；下次写点MySQl、PostgreSQL的文章吧。
